Answer:
The angles from largest to smallest are:
∠A
∠B
∠C
Step-by-step explanation:
We can see in the diagram that
AB = 7
AC = 8
BC = 9
The angles opposite to sides are as follows:
∠A is opposite to BC
∠B is opposite to AC
∠C is opposite to AB
The angle opposite to the largest side of the triangle is the largest and the angle opposite to smallest side of the triangle is the smallest in measurement
Arranging the sides from largest to smallest:
BC, AC, AB
Similarly the angles opposite them will be arranged according to them
∠A, ∠B, ∠C
Hence,
The angles from largest to smallest are:
∠A
∠B
∠C

Eleven minus four equal seven
11-4=7
Answer:
y = - 1/2x + 1
Step-by-step explanation:
y+2= - 1/2x
Slope = -1/2
Point: (-2,2)
y-Intercept: 2 - (-1/2)(-2) = 2 - 1 = 1
Answer:
-5
Step-by-step explanation:
3x -3 = -9 + 4 = -5
